PRES-2775: Fixes a problem which could prevent an upscaled Presto cluster from downscaling if short-running queries were regularly scheduled.

PRES-2727: Fixes a problem that caused queries to fail when a table contained sub-columns of type struct with names starting with a number.

PRES-2915: Fixes an issue which caused an ArrayIndexOutOfBoundsException for some queries using dynamic filtering.

HIVE-4681: Fixes a race condition which caused Thrift Metastore Server to fail to start.

ACM-5167: Fixes a problem that caused data disks to persist after a cluster had been terminated.

Enhancement

PRES-2600:

  • You can now set session properties in Presto notebooks. They will persist across paragraphs in a notebook.
  • To improve debugging, a source field is identified as notebook_<notename>_<note_id> for notebooks and dashboard_<dashboard_name>_<dashboard_id>_<source_note_id> for dashboards. A source field is directly searchable in the Presto UI; you can search a notebook by its name or ID to quickly filter queries when debugging.

PRES-2254: You can now set the zeppelin.presto.stacktrace interpreter property to see the stack trace for some errors.

JDBC-124: Adds support for multiple statements launched together in Fastpath.

May 30 2019 2:34 AM PST 56.0.1013 R56 release
May 2 2019 2:06 AM PST 50.0.1006 Bug fix

AN-1974: Column headers now appear on the Analyze page for large Hive queries (approximately 65KB and greater).

AN-1667: Provides faster data preview in the Analyze preview pane.

Enhancement AN-1751: Adds Examples tab on the Analyze page.
Mar 27 2019 01:38 AM PST 55.0.1001 Bug fix PRES-2635: An earlier fix to improve the planning time of queries which use the CONCAT function caused a degradation in execution in some cases. The current fix disables the planning optimization by default; to enable it, enable qubole.skip-concat-partition-pruning as a Presto cluster override. You can also enable it for a session by setting qubole.skip-concat-partition-pruning as a session property.
March 14 2019 2:18 AM PST 54.0.1000 R55 release
January 14 2019 6:02 AM PST 54.0.1008 Bug fix PRES-2443: Fixes an issue that caused a Presto query to fail if it needed to launch a cluster (though the cluster itself eventually came up).
November 28 2018 1:35 PM PST 54.0.1002 R54 release
